With +-47.5Vdc (which varies markedly with mains voltage variations) expect maximum output voltage to be ~40Vpk.

40Vpk into 8r0 is equivalent to 100W into 8r0.

With 2x47.5V AC maximum output power is 240W into 8R or 480W into 4R...

47.5-0-47.5 volts
I read that as DC voltage available from the PSU.
You read that as AC voltage from the transformer.
Which?

What is DC rail voltage on your PSU or what is AC voltage on your transformer?

No, they are only 100V.

The design requires 150V parts for 67V.
